| [the mechanisms of the anti-ulcer action of plant drug agents]. | the mechanisms of the gastroprotective effect of well-known drugs (plantaglucid, befungin, plantain juice), extractions of birch bark (betula pendula roth,) and burdock seeds (arctium tomentosum mill.) on various links of gastric ulcer pathogenesis were compared. phytopreparations were found to have a variety of effects on gastric secretion in rats. differences in their action on the smooth muscles of the stomach and intestine were detected. | 1999 | 10513334 |
| anatomy of subterranean organs of medicinally used cardueae and related species and its value for discrimination. | numerous species of the asteraceae, the composites, are famous for their use in both traditional and conventional medicine. reliable anatomical descriptions of these plants and of possible adulterations provide a basis for fast identification and cheap purity controls of respective medicinal drugs by means of light microscopy. nevertheless, detailed comparative studies on root and rhizome anatomy of valuable as well as related inconsiderable composite plants are largely missing yet. the presente ... | 2011 | 21617780 |
| carbon and nitrogen partitioning in the biennial monocarp arctium tomentosum mill. | growth and nitrogen partitioning were investigated in the biennial monocarp arctium tomentosum in the field, in plants growing at natural light conditions, in plants in which approximately half the leaf area was removed and in plants growing under 20% of incident irradiation. growth quantities were derived from splined cubic polynomial exponential functions fitted to dry matter, leaf area and nitrogen data.main emphasis was made to understanding of the significance of carbohydrate and nitrogen s ... | 1986 | 28311937 |

| carbon dioxide assimilation in the flowerhead of arctium. | the gas exchange of flowerheads was determined in arctium tomentosum and a. lappa during their development. the light, temperature and co2 responses were used to estimate flowerhead photosynthesis and the in situ contribution of carbon assimilation to the carbon requirement of the plant for supporting a flowerhead. changes in vapour pressure deficit had no effect on flowerhead photosynthesis rates and were not included in the model.in both species assimilatory capacity correlated with total brac ... | 1987 | 28311413 |
| nitrogen and carbohydrate storage in biennials originating from habitats of different resource availability. | four biennial species (arctium tomentosum, cirsium vulgare, dipsacus sylvester and daucus carota) which originate from habitats of different nutrient availability were investigated in a 2-year experiment in a twofactorial structured block design varying light (natural daylight versus shading) and fertilizer addition. the experiment was designed to study storage as reserve formation (competing with growth) or as accumulation (see chapin et al. 1990). we show that (i) the previous definitions of s ... | 1993 | 28313438 |
| small-rna deep sequencing reveals arctium tomentosum as a natural host of alstroemeria virus x and a new putative emaravirus. | arctium species (asteraceae) are distributed worldwide and are used as food and rich sources of secondary metabolites for the pharmaceutical industry, e.g., against avian influenza virus. rna silencing is an antiviral defense mechanism that detects and destroys virus-derived double-stranded rna, resulting in accumulation of virus-derived small rnas (21-24 nucleotides) that can be used for generic detection of viruses by small-rna deep sequencing (srds). | 2012 | 22912734 |
| evaluation of cotton burdock (arctium tomentosum mill.) responses to multi-metal exposure. | plants have immense potential for their use in the minimization of emerging environmental pollution issues. under simulated laboratory conditions, this work investigated the growth and biochemical responses of 14-day-old cotton burdock (arctium tomentosum mill.) seedlings to the body burdens of multi-metals including pb, cu, ni, and zn (1.0 μm-10 mm). biochemical traits (superoxide generation, lipid peroxidation, content of total peroxides), growth traits (axial organs growth, dry weight accumul ... | 2017 | 28028699 |
| genetic and morphological differentiation in tephritis bardanae (diptera: tephritidae): evidence for host-race formation. | the fruit fly tephritis bardanae infests flower heads of two burdock hosts, arctium tomentosum and a. minus. observations suggest host-associated mating and behavioural differences at oviposition indicating host-race status. previously, flies from each host plant were found to differ slightly in allozyme allele frequencies, but these differences could as well be explained by geographical separation of host plants. in the present study, we explicitly test whether genetic and morphological varianc ... | 2004 | 15000651 |
